Really, IMO, you can probably use ANY fixed blade broadhead and not have to worry about penetration as long as you avoid the shoulder, with the setup in your signature. I'd say the better question would be "how much time am I willing to invest in tuning my bow to a larger, more unforgiving broadhead?" If your willing to spend the time, go with big fixed blade head. As for that particular mechanical, I agree they are junk, but not because of the blood trails they leave. I double lunged a doe with one, and the blood trail was awesome, but the head was completely trashed, and broken at the ferrule. 15 yard shot, didnt hit any ribs, and went into the sandy ground straight. But what do you expect for $12 for 3 pack of broadheads. You get what you pay for.
